Oneera

Nice start-up building real-time maps of venues open to the public

Oneera builds real-time maps of festivals, clubs and other venues open to the public. Visitors find their way and locate their friends with a QR code; organisers monitor crowd density, receive incident reports and coordinate their teams from a dashboard.

Founded in Nice in May 2026 by Junior William Joyant, the company ran its first trials in Cannes clubs and is considering opening 20 to 30% of its capital to investors.
